Subject: Re: [PATCH v4 00/25] md: improve lockless bitmap reshape support
Date: Sun, 2 Aug 2026 18:13:08 +0200 [thread overview]
Message-ID: <20260802161310.8097-1-mykola@meshstor.io> (raw)
In-Reply-To: <20260801172519.2982121-1-yukuai@kernel.org>
Hi Kuai,
I ran v4 through the same rig as v2. All 25 patches applied cleanly
and build individually, the four problems I reported against v2 stay
fixed, and extra tests aimed at v4's new code (the raid5 boundary
split, the resize quiesce, the new reshape_lock under PROVE_LOCKING)
were all clean.
If raid10 tests on this base hit KASAN in free_r10bio(), that is Chen
Cheng's separate r10bio bug, not this series; with the fix from
latest md-7.3 the same tests are clean.
Tested-by: Mykola Marzhan <mykola@meshstor.io>
Thanks,
Mykola
